Abstract: A method and device is provided for measuring dust in a flowing gas, particularly atmospheric air. The device includes an intake nozzle which is configured such that aerodynamic forces continuously position the intake nozzle along the direction of gas flow. The velocity of the measuring stream in the inlet of the intake nozzle is compared with the velocity of gas flowing around the intake nozzle. The possible difference between the measured velocities is compensated by changing the velocity of the measuring stream in a mechanical way such as with a suction pump.

Abstract: The present invention discloses a method and device for measuring dust concentration in flowing gas, particularly atmospheric air. Aerodynamic forces continuously position the intake nozzle (2) along the direction of gas flow. The velocity of the measuring stream in the inlet of the intake nozzle (2) is compared with velocity of gas flowing around the intake nozzle (2) and the possible difference is compensated by changing the velocity of the measuring stream in mechanical way.
